051e84c4b4 Move server API concept to base framework
This commit introduces the new `Component` interface in the form of the
headers base/component.h and base/entrypoint.h. The os/server.h API
has become merely a compatibilty wrapper and will eventually be removed.
The same holds true for os/signal_rpc_dispatcher.h. The mechanism has
moved to base/signal.h and is now called 'Signal_handler'.

Since the patch shuffles headers around, please do a 'make clean' in the
build directory.

cda07b7da0 base: simplification of the IPC code
This commit replaces the stateful 'Ipc_client' type with the plain
function 'ipc_call' that takes all the needed state as arguments.
The stateful 'Ipc_server' class is retained but it moved from the public
API to the internal ipc_server.h header. The kernel-specific
implementations were cleaned up and simplified. E.g., the 'wait'
function does no longer exist. The badge and exception code are no
longer carried in the message buffers but are handled in kernel-specific
ways.

2490e399dc ldso: check binary pointer before lookup
Check if the binary pointer is valid before attempting to lookup the

e.g a library that references 'errno' but is not linked against libc,
will now produce an error message when they are loaded by the dynamic
linker.

7f73e5e879 base: hide internals of the Thread API
This patch moves details about the stack allocation and organization
the base-internal headers. Thereby, I replaced the notion of "thread
contexts" by "stacks" as this term is much more intuitive. The fact that
we place thread-specific information at the bottom of the stack is not
worth introducing new terminology.

This patch establishes a common organization of header files
internal to the base framework. The internal headers are located at

62b1c55399 Integrate CAP session into PD session
This patch integrates the functionality of the former CAP session into
the PD session and unifies the approch of supplementing the generic PD
session with kernel-specific functionality. The latter is achieved by
the new 'Native_pd' interface. The kernel-specific interface can be
obtained via the Pd_session::native_pd accessor function. The
kernel-specific interfaces are named Nova_native_pd, Foc_native_pd, and
Linux_native_pd.

The latter change allowed for to deduplication of the
pd_session_component code among the various base platforms.

To retain API compatibility, we keep the 'Cap_session' and
'Cap_connection' around. But those classes have become mere wrappers
around the PD session interface.

ff10687a6c toolchain: report missing ports at once
Previously, ports that were needed for a scenario and that were not
prepared or outdated, triggered one assertion each during the second
build stage. The commit slots a mechanism in ahead that gathers all
these ports during the first build stage and reports them in form of a
list before the second build stage is entered.  This list can be used
directly as argument for tool/ports/prepare_port to prepare respectively
update the ports. If, however, this mechanism is not available, for
example because a target is build without the first build stage, the old
assertion still prevents the target from running into troubles with a
missing port.

d424134073 cxx: Simplify C++ exception wrapper functions
The wrapper functions (e.g., 'Unwind_*' and friends) now have the same signature
as the original function in 'libgcc', reside in a separate C file which is
archived to cxx.lib.a. In supc++.o we prefix the wrapped functions with '_cxx_'.

This also enables support for riscv.

7aff1895bf hw: enable SMP for ARM Cortex A9
This commit enables multi-processing for all Cortex A9 SoCs we currently
support. Moreover, it thereby enables the L2 cache for i.MX6 that was not
enabled until now. However, the QEMU variants hw_pbxa9 and hw_zynq still
only use 1 core, because the busy cpu synchronization used when initializing
multiple Cortex A9 cores leads to horrible boot times on QEMU.

During this work the CPU initialization in general was reworked. From now
on lots of hardware specifics were put into the 'spec' specific files, some
generic hook functions and abstractions thereby were eliminated. This
results to more lean implementations for instance on non-SMP platforms,
or in the x86 case where cache maintainance is a non-issue.

Due to the fact that memory/cache coherency and SMP are closely coupled
on ARM Cortex A9 this commit combines so different aspects.

23f9761297 base: minimize critical section in Semaphore::up
When unblocking a thread in Semaphore::up() while holding the fifo meta-data
lock, it might happen that the lock holder gets destroyed by the one it was
unblocking. This happened for instance in the pthread test in the past, where
thread destruction was synchronized via a semaphore. There is no need to hold
the lock during the unblock operation, so we should do it outside the critical
section.

492bd39619 epit timer: raise precision
Previously we used a pretty slow external clock source for the timer. This
resulted in such a low TICS_PER_MS value that the granularity wasn't
sufficient to find a setup with a precision better than 1 second error per
minute. Now we use the so-called High Frequency Reference Clock as input
with TICS_PER_MS=33333 and the timer precision is significantly < 1 second per
minute.

d65beb970d dde_linux: KMS-based Intel framebuffer driver (II)
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs

The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax

  <config>
    <connector name="LVDS-11" width="1280" height="800" enabled="true"/>
  </config>

Also, when enabled within the intel framebuffer driver configuration like
the following

  <config buffered="yes"/>

a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.

The  driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows

  <connectors>
    <connector name="LVDS-11" connected="1">
      <mode width="1280" height="800" hz="60"/>
      ...
    </connector>
    ...
  </connectors>

The driver distributes the report only if this is stated within its
configuration, like the following

  <config>
    <report connectors="yes"/>
  </config>
